ABSTRACT
The seismic data acquired from a high resolution survey realized at the access channel to
the Patos lagoon, showed the presence of coastal barriers structures, characterizing the
presence of old transgressive-regressive sandy bodies that, in the past, blocked the
current communication between Patos lagoon and the Atlantic ocean. The interpretation
of the seismic profiles allowed the identification of three overlapped sedimentary
sequences distributed along the channel. The presence of this kind of structure evidences
that the current communication access between Patos lagoon and the Atlantic ocean was
done through a more south channel, skirting the Marinheiros´s island, which was part of
the Barrier III, and drainned at south part of Cassino´s beach. The presence of these
prograding structures contribute to characterize the coastal region evolution, mainly the
area of the current access channel between the lagoon and the sea.
